The auxillary pump (and fan) is apparently set to run when the engine is
turned off and the coolant temperature reaches 110C and shuts off at
97C. I've never witnessed this happening as 110C is pretty high. Has
anyone tried replacing the thermo switch as per the S4tt (see link) to
come on at a lower temperature? This seems like a good idea to me.
Anyone have part numbers?
